Abstract

A steam turbogenerator set includes a common shaft for a steam turbine and a driven machine with a generator, downstream of which a frequency converter is connected. Electrical power can be fed at a predetermined frequency through the frequency converter into a load network. Bearings of the common shaft are cooled and lubricated with water. Since there is no gearing requiring cooling and lubricating, and control valves for the steam are also driven without oil, the risk of contamination or fire caused by oil is avoided. A method for operation of the steam turbogenerator set is also provided.
